Description
Technical Field
The utility model relates to the technical field of waterproof coiled materials, in particular to a multilayer co-extrusion thermoplastic polyolefin self-adhesive composite waterproof coiled material.
Background
Thermoplastic Polyolefin (TPO) waterproof coiled materials have good physical properties and excellent ageing resistance. The joint edges can be welded into a whole through hot air, so that the waterproof material has good integrity and is a novel high polymer waterproof material. There are generally homogeneous, backing and in-fabric reinforcement. With the development of the waterproof industry in recent years, more composite waterproof solutions are developed, and some of the waterproof solutions are compounded with asphalt-based self-adhesive coiled materials, some of the waterproof solutions are compounded with non-asphalt-based high-polymer hot-melt pressure-sensitive adhesives, and some of the waterproof solutions are compounded with butyl adhesives. The composite waterproof solutions can effectively improve the bonding capability between materials and other waterproof coiled materials or between the materials and a base surface, and can enhance the waterproof effect. A portion of Thermoplastic Polyolefin (TPO) waterproof rolls are also compounded with a coating (one-component polyurethane SPU or polymer cement JS waterproof coating) to form a roll composite waterproof system.
Whether asphalt-based hot melt adhesive, non-asphalt-based high polymer hot melt pressure-sensitive adhesive or butyl hot melt pressure-sensitive adhesive, a small amount of small molecular plasticizer is needed in the formula composition. Most of Thermoplastic Polyolefin (TPO) waterproof coiled materials are amorphous high molecular polymers, and most of molecular chain structures are amorphous and amorphous, if the waterproof coiled materials are not treated by proper technical measures, small molecular substances (oil or plasticizer) in a composite adhesive layer can easily enter a TPO layer through diffusion, so that the physical and mechanical properties of the TPO layer are reduced. The loss of small molecules can also change the components in the adhesive layer, so that the pressure sensitivity of the adhesive layer is reduced, and even the adhesive layer is lost. As can be seen, migration of small molecule oil is a very troublesome problem in composite waterproof rolls or waterproof systems.
